Abstract: The objective of this study was to determine the effect of vitamin E and selenium administration on glutathione peroxidase (GSH-Px) activity and selected parameters of cellular immunity (metabolic activity, phagocytic activity, lymphocyte blastogenic response). Nine pregnant sheep with body weight of 42 to 66 kg were divided into two groups. Before lambing, the first group (n = 5) was given subcutaneously 5 mg vitamin E and 0.4 mg selenium per kg body weight while the second group (n = 4) was given no treatment and served as control. Blood samples from all sheep were collected before the treatment, 14 days after lambing and 30 days after lambing. Whole blood GSH-Px activities were significantly higher in the vitamin E and selenium treated sheep than in the control in the samples taken 14 days after lambing and 30 days after lambing (P < 0.01; P < 0.001, respectively). The evaluation of immunological parameters showed declines in immunological parameters measured on days 14 and 30 after lambing. The administered preparation led to significant effects (P < 0.001; P < 0.05) on phagocytic activity index of leukocytes and phagocytic activity index of neutrophils, respectively.
